Specification of Letters Patent.

Patented Aug. 4:, 1914.

Application filed May 11, 1914. Serial No. 837,885.

To all whom it may concern Be it known that I, FRIEDRICH JULIUS Peri-is, engineer, a subject of the German Emperor, residing at Eichenstrasse 60, Hamburg, Germany, have invented new and useful Improvements in or Relating to Bottle- Closures, of which the followingjis a specification;

This invention relates to a bottle closure.

The bottle closure consists of a cap provided with lips and retaining tongues, and it is the object of the invention so to form the lips and tongues that when the cap is being placed in position over the bottlemouth the upper ends of the tongues will engage under the rim of the bottle neck, and when pressed against the bottle neck will pull the cap tightly over the bottle mouth and thus produce an effective gastight closure.

The invention 1s particularly suitable for the closure of bottles containingliquids under pressure. 1

The new bottle closure is illustrated in the accompanying drawings.

Figures 1 and? show sections of the bot tle necklwith the lips of the bottle closure in the open and closed positions respectively.

4: shows a side view at right angles to Fig. 3. The cap a of suitably strong tin is provided with a plurality of lips b two being shown in the exampleof construction illustrated. Each of these lips I) is provided with a tongue 0 produced by stamping a U? shaped slot in, the lips; the tongues being so formed that their lower ends remain firmly connected with their corresponding lips 79. In, order to strengthen the lips and the tongues the are provided for example with stamped ri s b c. The tongues c are so formed that their upper ends will engage under the rim f, and when they are pressed Copies ofthls patentniay be obtained 1'01 five cents each, by addressing the "Commissioner of Washington, D. 0.?

against the bottle neck the side members of the lips b will be pulled over the rim or shoulder s of the bottle, thus pulling the ca a downward and causing it to be gripped tightly on the bottle neck.

After the closure cap a has been provided with an insertion (Z of cardboard, cork or the like it is placed on the mouth f of the bottle 7 and is clamped thereon by any suitable closure applying mechanism The upper ends of the tongues 0 then rest under the rim 8 of the bottle mouth 7 and form supports for the closure cap a, so that it will retain the position into which it is brought by pressing the tongues 0 and lips 5 against the bottle neck, and cannot move even to a slight extent after the pressure exerted upon the cap a has beenremoved.

Thebottlemay also be provided with a protecting enlargement w which is formed as a flange on the bottle neck, and prevents accidental breakage of the closure device.

Having now described my invention what I claim as new and desire to secure by Let ters Patent is A bottle closure comprising a cap, with depending lips and upwardly extending tongues on said lips,and strengthening ribs on said lips and tongues, said tongues being so formed that they will engage withthe bottle rim and when pressed against the bottle neck will pull the cap downwardover the bottle mouth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses, this 16th day of April 1914.

FRIEDRICH JULIUS POTHS.
